Applications of high velocity airstreams for testing of products are often used for industrial and scientific research. Fans are used in laboratories studying environmental and meteorological results from a proposed technology. Fans can be selected to provide low flows at high velocities and/or high airflows at low to medium velocity. High volumes are most often going to require axial flow fans for space saving connections or recirculation of air in the test cell. High pressure tests can require centrifugal fan designs. NYB knows how to provide the fans to complete your application.
